What is oil shale and how was it formed

Most oil shale deposits were formed during Middle Cambrian, Early and Middle Ordovician, Late Devonian, Late Jurassic, and  Oil shale is a fine grained sedimentary rock formed from the compaction and heating of organic rich sediments and containing significant amounts of kerogen. 4 Mar 2013 Oil-bearing shales are underground rock formations that contain trapped petroleum. The petroleum trapped within the rocks is known as “tight oil” 

Oil shale. Formation of oil shale. Australian Deposits Torbanite Tasmanite Toolebuc Eastern Queensland Refining the oil shale. Oil / Tar Sands Oil Sand Formed in the Early Ordovician marine basin some 480 million years ago, it is much older than kukersite. Owing to the lack of organic matter, the calorific value of  The development of "oil shale" (not to be confused with "shale oil") and "tar sands " has been shown to be environmentally destructive, and water and energy  Oil Shale. The Bureau of Mines defines "oil shale" as a laminated, sedimentary rock-that is, a rock formed by excessive geologic deposits of clay, mud, and other   Oil shale refers to crude oil trapped in sedimentary rock. The petroleum Kerogen itself is usually formed from algae and other marine plant life. Kerogen is a 

29 Jun 2009 Four large oil shale deposits of the world (the largest?) were deposited in Eocene lakes of the U.S. Rocky Mountains (Green River. Formation) 

The most bountiful oil shale beds in the world lie in basins within the Green River Formation along the T-shaped border of Colorado, Wyoming, and Utah. The  Shale oil, Resources, Reserves, Combustion, Origin, Formation, Algae, Sapropel, The shale ash formed can be used for making cement and brick, and also  Potential Green River Formation oil shale reserves based on 30 gallons per ton of rock are almost 20 billion barrels of oil. Currently, only a few companies are  Potential Green River Formation oil shale reserves based on 30 gallons per ton of rock are almost 20 billion barrels of oil. Shale Oil. So what is shale oil? It's just   In fact, any shallow rock yielding oil in commercial amount upon pyrolysis is considered to be an oil shale. B. P. Tissot et al., Petroleum Formation and Occurrence. 3 Mar 2015 Oil shale is a mixture of sand, silt, salt, and an insoluble organic substance called kerogen. Rock-like at room temperature, oil shale produces  Many companies were formed to develop oil shale deposits of the Green River Formation in western United States, especially in Colorado. The US has an 

Shale oil is a crude oil that's trapped within layers of shale rock. It's produced by fracturing the rock and extracting the oil.

Most oil shale deposits were formed during Middle Cambrian, Early and Middle Ordovician, Late Devonian, Late Jurassic, and Paleogene times through burial by sedimentary loading on top of the algal swamp deposits, resulting in conversion of the organic matter to kerogen by diagenetic processes. Oil shale is commonly defined as a fine-grained sedimentary rock containing organic matter that yields substantial amounts of oil and combustible gas upon destructive distillation. Most of the organic matter is insoluble in ordinary organic solvents; therefore, it must be decomposed by heating to release such materials. Oil Shale. Oil shale is a rock that contains significant amounts of organic material in the form of kerogen. Up to 1/3 of the rock can be solid kerogen. Liquid and gaseous hydrocarbons can be extracted from oil shale, but the rock must be heated and/or treated with solvents. Shale oil is a crude oil that's trapped within layers of shale rock. It's produced by fracturing the rock and extracting the oil. Oil shale shouldn't be confused with "shale oil," also called “tight oil,” a more commonly produced type of unconventional oil that's found trapped in limestone or sandstone rocks. Because oil shale requires mining and energy-intensive refining processes, it's a substantially dirtier energy source than conventional liquid oil.

Oil shale was formed in the distant past by the simultaneous deposit of silt and organic debris on lakebeds and sea bottoms. As the raw materials accumulated,  

Shale oil is a high-quality crude oil that lies between layers of shale rock, impermeable mudstone, or siltstone. Oil companies produce shale oil by fracturing the rock formations that contain the layers of oil. Most oil shale deposits were formed during Middle Cambrian, Early and Middle Ordovician, Late Devonian, Late Jurassic, and Paleogene times through burial by sedimentary loading on top of the algal swamp deposits, resulting in conversion of the organic matter to kerogen by diagenetic processes.

13 Apr 2006 formation is estimated to contain more than 8 trillion barrels of shale oil in place; however, much of the formation has been considered too thin, 

Oil shale refers to crude oil trapped in sedimentary rock. The petroleum Kerogen itself is usually formed from algae and other marine plant life. Kerogen is a  Major resources of oil shale occur in ancient lakebeds of the Green River Formation in Colorado, Utah, and Wyoming. Although the resource potential of Nevada  of oil shale from the Green River Formation. The new study assumed a smaller industry of 500,000 bbls/day, with a mix of 40% ex-‐situ, 45% in-‐situ, and 15%
